Subject: [dpdk-dev] [PATCH v3 1/3] doc: add FEC in NIC features
Date: Fri, 29 Jan 2021 17:22:03 +0800
Message-ID: <1611912125-18216-2-git-send-email-oulijun@huawei.com> (raw)
In-Reply-To: <1611912125-18216-1-git-send-email-oulijun@huawei.com>

From: "Min Hu (Connor)" <humin29@huawei.com>

Document FEC in NIC features, add information about FEC and add
implementation related support.

Fixes: b7ccfb09da95 ("ethdev: introduce FEC API")
Fixes: 9bf2ea8dbc65 ("net/hns3: support FEC")
Fixes: 62aafe035896 ("net/cxgbe: support configuring link FEC")
Cc: stable@dpdk.org

V2->V3:
- merge patch 2 and patch 3 into patch 1 according to Thomas Monjalon's
  advice.
- fix format errors in hns3.ini and cxgbe.ini

V1->V2:
- add Fixes for indicating that the driver is updated synchronously.

+Supports Forward error correction. Forward error correction (FEC) is a bit error correction mode.
+It adds error correction information to data packets at the transmit end, and uses the error correction
+information to correct the bit errors generated during data packet transmission at the receive end. This
+improves signal quality but also brings a delay to signals. This function can be enabled or disabled as required.
